Title: Process for the manufacture of modified polyvinyl alcohols
IPC: C08F8/12
Filed: 1960-12-23
Abstract: A modified polyvinyl alcohol is prepared by subjecting a copolymer of a vinyl ester of a saturated carboxylic acid and an olefinically-unsaturated phosphonic acid dialkyl ester to alcoholysis with methanol and a mixture of methanol and methyl acetate, in the presence of 0 to 15 % water (calculated on the weight of copolymer) at 15 to 90 DEG C. until at least 80% of the ester groups are converted into vinyl alcohol groups.  More than one ester may be present in the copolymer and the formate, propionate, butyrate, stearate and acetate are specified while other comonomers e.g. vinyl chloride, ethylene, isobutylene, and acrylic, methacrylic, maleic and fumaric esters.  The phosphoric acid esters may be diesters of ethene-, propene-, or allyl-phosphonic acid.  An alcoholysis catalyst e.g. sodium hydroxide, and alkali metal alcoholates or hydrochloric, perchloric, sulphuric, trichloroacetic and dodecyl benzenesulphonic acid may preferably be present.

Patent GB-927052-A (GB)
Title: Improvements in or relating to a continuous process and apparatus for producing artificial textile filaments
Inventor: SCRAGG FREDERICK
IPC: D01D5/00
Filed: 1960-12-28
Abstract: A cast branched artificial filament, particularly a cast filament consisting of a trunk or main continuous portion from which diverge numerous relatively short branch portions integral therewith (as shown, for example, at 14 and 11 in the drawings, not shown) is continuously produced by continuously ejecting on to that portion of the inner surface 13 of a hollow rotating cylinder 12 which is engraved with a circumferential recessed pattern track 14 lying in a plane normal to the axis of rotation of the cylinder a stream of a molten organic filament-forming material (or a solution of such a material in a volatile solvent) from a nozzle 16, the cylinder being rotated at an angular velocity sufficiently high to generate a centrifugal force acting on the material deposited in the track sufficient to cause the material to be forced into the track so that the material becomes cast therein as in a mould in the shape of the filament, and solidifying the cast material by cooling if it is a melt, or by evaporation of the solvent by heating if it is in the form of a solution.  The cast branched filament thus produced is then stripped from the track by a scraper 17 and removed from the interior of the cylinder in an axial direction.  If the filament-forming material is ejected from the nozzle in the form of a melt, the portion of the cylinder passing through the casting zone may be heated in order to ensure that the melt flows into the track in a thorough manner, and the portion of the cylinder subsequently passing through the stripping zone may be cooled to solidify the melt in the track prior to stripping it therefrom. If the filament-forming material is ejected from the nozzle in the form of a solution in a volatile solvent, the latter may be evaporated by sweeping the inner surface of the cylinder with a stream of a heated gaseous evaporative medium such as air.  A number of branched filaments may be cast simultaneously in the cylinder, a nozzle and track being provided for each filament. The removal of these filaments from the cylinder causes twisting to take place so that the emerging yarn can be provided with an amount of twist which is determined by the diameter of the rotating cylinder.  The rate of ejection of the filament-forming material or solution is preferably not greater than suffices to fill the recesses of the track with the material.  The filament-forming material ejected from the nozzle may be in the form of a solution in a solvent from which it is thereafter precipitated by contacting the solution occupying the track with a coagulating liquid.  Specification 924,517 is referred to.

Abstract: 1440143 Continuous casting SPECIAL METALS CORP 2 Oct 1973 [3 Oct 1972] 45996/73 Heading B3F [Also in Divisions G3 and H5] In a method of continuous casting, the molten metal is produced by melting a consumable electrode 52 at a controlled rate within a controlled atmosphere, e.g. a vacuum. In the embodiment shown in Fig. 1, an arc is struck between the electrode 52 and a cooled non- consumable stool 54, the molten metal produced flowing into a heated tundish 10 provided with a baffle 14 and nozzle 15 and then into a mould 16. The billet produced is withdrawn from the mould by pinch rolls 19 and passes out of the vacuum chamber 23 via a seal 24 consisting of a plurality of vacuum chambers each connected to a vacuum line 25a, 25b, 25c. It may be cut into lengths by a blade 26. The level of metal in the mould is sensed by a transducer 43 and the speed of the motor 21 driving the pinch rolls 19 adjusted in accordance with the signal from the transducer to maintain the metal level within predetermined limits. The rate of melting of the electrode 52 and thus the rate at which metal is supplied to the mould may be adjusted by changing the power input to the electrode by means of a potentiometer 33. In an embodiment, Fig. 3, the molten metal is formed by striking an arc between two consumable electrodes 12 and 13 which are oscillated or rotated about their longitudinal axes by motors 70 and 69. The gap between the electrodes is maintained constant by hydraulic drives 36 and 37 connected to a servo system 40. The polarities of the electrodes may be changed periodically by means of a reversing switch 71.
